‘Supergirl’ Season 4: The CW Show Gets A New Action-Packed Trailer!! Check It Out!!

With Supergirl set to return to The CW this Sunday, an action-packed new trailer has arrived online for the fourth season of the DC superhero series, which you can watch here:

Season three saw Supergirl stop Reign and the other Worldkillers’ threat to humanity and our planet, and in the process, Kara was shocked to find her mother Alura alive and living in a salvaged Argo City that survived the destruction of Krypton. Reconnecting with her past caused Kara to realize that her true home is now here on Earth, where big changes are taking place for her and all of her friends in National City – and also, it appears, for a doppelganger in Russia! Season four promises to be full of surprises, action, adventure and lots of big revelations for Supergirl, Alex, James, J’onn, Lena and Brainy.
